Step-by-step explanation:
Answer:
The expected ratio: 8/60 = x/2400
=> The number of flawed wrenches in a batch of 2400:
x = 2400*8/60 = 320
This problem is half understanding the question and half just plugging in numbers.
Understanding the Question:So its saying that n = whole number bigger than one, making n = 2, 3, 4, 5, etc.
Now try plugging any number n into the
equation. Let's use 2 to make it simple. If you plug in 2, you get:
Remember that the subscripts (the small numbers in the corner) are simply the term number.
is term 1,
is term 2, etc. The equation is saying that "term 2 = 4 times term 1."
If you keep plugging in random numbers for n, you'll see that the equation basically says, "a term = 4 times the term right before it." That makes it easy to plug and chug to get our answer.
Plugging and Chugging
Now we understand the question is asking for the first 4 terms, and each term is 4 times the last term. You're told that term 1,
= 6. That makes the next four terms:
Term 2
Term 3
Term 4
Your first 4 terms are 4, 24, 96, and 384.

Answer: A) F
Let AB = t. And since X lies in the middle, so AX=BX = t/2 .
Let the height of the smaller flagpole is AO and of larger flagpole is BP .
Using tangent ratio rule in each triangle, we will get
And there ratio is
4 x 4 = 16
